All above and below ground materials must be removed. The ground must be restored to its original condition within 60 days of abandonment. Security: If a license is approved pursuant to this Ordinance, the Township Board shall require security in the form of a cash deposit or irrevocable letter of credit (in a form, amount, time duration and with a financial institution deemed acceptable to the Township), which will be furnished by the applicant to the Township in order to ensure full compliance with this Ordinance and any conditions of approval. When determining the amount of such required security, the Township may also require an annual escalator or increase based on the Federal Consumer Price Index (or the equivalent or its successor). Such financial guarantee shall be deposited or filed with the Township Clerk after a license has been approved but before construction commences upon a WECS or WECS Testing Facility. At a minimum, the financial security shall be in an amount determined by the Township Board to be sufficient to have the WECS or Testing Facility fully removed (and all components properly disposed of and the land returned to its original state) should such structure or structures become abandoned, dangerous or obsolete, or not in compliance with this Ordinance or the license approval. Such financial security shall be kept in full force and effect during the entire time while a WECS or WECS Testing Facility exists or is in place. Such financial security shall be irrevocable and non-cancelable (except by the written consent of both the Township and the then-owner of the WECS or WECS Testing Facility) for at least 30 years from the date of the license approval. Failure to keep such financial security in full force and effect at all times while a WECS or WECS Testing Facility exists or is in place shall constitute a material and significant violation of a license approval and this Ordinance, and will subject the applicant to all available remedies to the Township, including possible enforcement action and revocation of the license. Road repair: Any damages to a public road located within the Township resulting from the construction, maintenance, or operation of a WECS or Testing Facility shall be repaired at the applicant s expense. Liability: The applicant shall insure each WECS at all times for at least $2,000,000 (to be adjusted annually to an amount equivalent to 2012 dollars based on the federal CPI) for liability to cover the applicant, Township and land owner. - 8 -
(o) (p) (q) (r) (s) (t) (u) (v) Color: A WECS shall be painted a non-obtrusive (light environmental color such as beige or gray) color that is non-reflective. The wind turbine base and blades shall be of a color consistent with all other turbines in the area. No lettering, company insignia, advertising, or graphics shall be on any part of the tower, hub, or blades. Strobe effect (also known as shadow flicker): No WECS or Testing Facility shall cause any strobe effect or shadow flicker without written approval by the Township Board. Under no circumstances shall a WECS or Testing Facility produce vibrations or wind currents humanly perceptible beyond the property boundaries of the lot or parcel on which the WECS or Testing Facility is located. The applicant shall be responsible for compensation to persons damaged due to any stray voltage caused by a WECS. At the Township s request, the applicant shall fund an environmental assessment or impact study and/or other relevant report(s) or studies (including, but not limited to, assessing the potential impact on endangered species, eagles, birds, and/or other wildlife) as required by the Township for review by the Township regarding the area or surrounding areas where the WECS will be placed. Each such study or report shall be provided to the Township prior to the time when the Township Board makes its final decision regarding the license. At the Township s request, the applicant shall fund a financial impact study for review by the Township of the area affected by the WECS. Such study or report shall be provided to the Township prior to the time when the Township Board makes its final decision regarding the license. An escrow account shall be set up when the applicant applies for a license for a WECS or WECS Testing Facility. The monetary amount filed by the applicant with the Township shall be in an amount estimated by the Township to cover all costs and expenses associated with the license review and approval process, which costs can include, but are not limited to, fees of the Township Attorney, Township Planner and Township Engineer, as well as any reports or studies which the Township anticipates it may have done related to license review process for the particular application. Such escrow amount shall be in addition to regularly established fees. At any point during the license review process, the Township may require that the applicant place additional monies into escrow with the Township should the existing escrow amount filed by the applicant prove insufficient. If the escrow account needs replenishing and the applicant refuses to do so promptly, the license review and approval process shall cease until and unless the applicant makes the required escrow deposit. Any applicable zoning escrow resolutions or other ordinances adopted by the Township or by Clinton County shall also be applicable. Reasonable conditions: In addition to the requirements of this section, the Township Board may impose additional reasonable conditions on the approval of a license for a WECS or WECS Testing Facility. - 9 -
